Construction costs in Canada have risen roughly 67% over the past five years, according to industry data. For a property owner carrying loss of rent coverage, that statistic translates into a specific problem: it now costs significantly more and takes longer to rebuild or repair a rental property after a claim. If your policy’s loss of rent limit was set five years ago, it may cover only a fraction of the actual income you’d lose while waiting for repairs.

Loss of rent insurance is meant to replace the income you lose when a rental property becomes uninhabitable because of an insured event like a fire, flood, or storm. What many property owners don’t realise is that the same forces driving up construction costs — material prices, labour shortages, supply chain delays — also stretch out the time it takes to get a property back into rentable condition. That makes your loss of rent period longer and more expensive than your policy might be set up to handle.
And the market is shifting in ways that cut both ways. Commercial insurance rates in Canada have been falling — down 3% in the third quarter of 2025 alone, the seventh consecutive quarterly decline. That means now is a good time to adjust coverage. But a softer market also means you need to know exactly what you’re asking for, because the underlying hazards haven’t gone anywhere. Here’s what you actually need to know.
Before digging into the numbers, it helps to be clear on the central concept. Loss of rent insurance — also called rental income coverage or, in commercial policies, time element coverage — replaces the rental income you lose when a property can’t be occupied due to an insured peril. It doesn’t pay for the physical damage itself. That’s what your building policy is for. Loss of rent kicks in for the period between when the property becomes uninhabitable and when it’s back in rentable condition, up to the limit and indemnity period stated in your policy.
What I tend to notice is that most property owners understand the idea of covering the building itself. The rental income piece often gets less attention, even though for many landlords it’s the bigger financial exposure. A rental property that sits empty for six months while being rebuilt doesn’t just lose one month’s rent — it loses six, plus any additional expenses like mortgage payments that keep running regardless.
Co-insurance penalties and how they actually affect your claim
The co-insurance clause is the most consequential number in most property policies, yet it’s the one people skip over during renewal. Found in nearly all commercial and many residential policies, it requires you to insure your property to a specific percentage of its replacement value — typically 80% or 90%. If you don’t, the insurer treats you as a co-insurer on every claim.
Here’s how the math works. Say your rental property would cost $3 million to rebuild in 2026, but you insured it for $2 million based on a valuation from 2021. You suffer a partial loss — fire damage that costs $500,000 to repair. With an 80% co-insurance clause, the insurer calculates what you should have carried: 80% of $3 million, which is $2.4 million. You carried $2 million. The formula is (2,000,000 ÷ 2,400,000) × $500,000 = $416,667. That’s your payout. You’re out $83,333 — a 16.7% penalty on a partial loss.
If the loss were total, the gap would be far worse. The same formula on a $3 million total loss with a $2 million policy limit gives you (2,000,000 ÷ 2,400,000) × $3,000,000 = $2.5 million — except your policy only pays up to its $2 million limit, so you’d lose $1 million outright.
If your insured amount falls below the required percentage of replacement cost, you absorb a proportional share of every loss — not just the difference, but a percentage of the whole claim.

| Replacement Cost | Amount Insured | Co-insurance Penalty on $500K Loss |
|---|---|---|
| $3,000,000 | $2,000,000 | $83,333 (16.7%) |
| $3,000,000 | $2,400,000 | $0 (fully compliant) |
| $3,000,000 | $1,500,000 | $187,500 (37.5%) |
This is where the 67% construction cost increase hits hardest. A property valued at $1.8 million in 2021 may well cost $3 million to rebuild today. If your policy limit stayed flat, you’re not just underinsured on the building — you’re also triggering a co-insurance penalty on every loss of rent claim tied to that building. The loss of rent coverage is typically calculated as a percentage of the building limit, so it shrinks in step.
Data from the property insurance market shows that commercial rates have been declining, with double-digit reductions common for well-managed risks. But a lower premium on an underinsured policy isn’t a bargain — it’s a trap. The 2026 outlook from several brokers emphasises that underwriters are still focused on valuation accuracy, and data quality matters more than ever for securing favourable terms.
Errors and gaps that cost property owners real money
Setting indemnity periods based on optimistic timelines
Your loss of rent coverage only pays for a specific period — usually 12, 18, or 24 months from the date of loss. Many property owners pick the shortest period thinking repairs will be quick. But construction costs up 67% mean longer rebuild times. Materials take longer to source, contractors are booked further out, and permits involve more steps. A 12-month indemnity period that seemed generous in 2021 might leave you with no income for the last four months of a rebuild. If you’re carrying a mortgage on that property, those months still cost you.
Assuming Guaranteed Replacement Cost covers everything
The Emond v. Trillium Mutual Insurance Co. decision from early 2026 clarified a critical point: a Guaranteed Replacement Cost endorsement does not override the compliance cost exclusion in your base policy. That exclusion limits coverage for increased costs due to building codes, zoning bylaws, or energy efficiency standards that were enacted after your property was built. In practice, modern building codes can add $100,000 or more to a rebuild. Before Emond, some public adjusters successfully argued that GRC covered these costs. After Emond, insurers are capping them at the standard sub-limit — often as little as $10,000 or $25,000. That cap directly affects loss of rent too, because any delay caused by compliance disputes extends the time your property sits empty.
Failing to review declared values before renewal
What I tend to notice is that property owners update their building values when they buy a policy and then don’t touch them again. But the gap between declared values and actual replacement costs has widened dramatically. A Spring 2026 market update from Aon notes that up-to-date valuations are a key factor in unlocking improved terms. If you haven’t had a professional valuation done in the last two years, your declared value is almost certainly too low. The fix is straightforward: request a replacement cost valuation from a qualified quantity surveyor or appraiser before your next renewal. Submit that updated figure to your insurer. It may raise your premium slightly, but it eliminates the co-insurance penalty risk entirely.
Overlooking the “technique vs. law” distinction
After Emond, public adjusters are drawing a finer line between cost increases caused by laws (zoning setbacks, code requirements) and those caused by current building techniques (modern truss systems, standard construction methods). If a cost increase is due to a law, the compliance exclusion applies. If it’s due to technique — the way builders actually build today — it falls under the GRC endorsement. This distinction matters for loss of rent because the longer the dispute over what’s covered, the longer the property stays uninhabitable. Getting a clear policy wording review from your broker can save months of back-and-forth.
How to assess and structure loss of rent coverage properly
Calculate the right loss of rent limit
Your loss of rent limit should be based on the actual rent you’d lose, plus any additional expenses, over a realistic rebuild timeline. Don’t use your current rent roll as the only input. Factor in:
- Monthly rental income from all units
- Expected rent increases over the next 12–24 months
- Mortgage, utilities, and property taxes that continue during vacancy
- Estimated rebuild time based on current construction timelines, not historical averages
Once you have that number, multiply it by the longest plausible indemnity period — 24 months is safer than 12 for most rental properties today. The premium difference between 12 and 24 months is usually modest compared to the cost of running out of coverage mid-rebuild.
Review time element provisions and extensions
Standard loss of rent coverage includes the basic indemnity period, but you may also need extensions for civil authority, ingress/egress, and service interruption. If a municipal order blocks access to your property after a neighbouring fire, or if a utility outage prevents occupancy, basic loss of rent may not respond unless these extensions are on your policy. The WTW report on Canadian property insurance specifically flags these provisions as areas where coverage gaps commonly occur. Go through each one with your broker and confirm the sub-limits are adequate.
Use the soft market to lock in better terms
With commercial rates falling and property placements frequently oversubscribed by nearly 50%, insurers are more willing to negotiate. This is a good time to ask for:
- Longer indemnity periods at no additional premium
- Higher sub-limits for compliance cost coverage
- No-claims bonuses or engineering credits
- Long-term rate agreements that lock in the current soft market pricing
Top-tier accounts with strong loss histories have been achieving decreases exceeding 20% when fully marketed. If you’ve invested in property security measures like monitored alarms or leak detection systems, make sure your broker highlights those to underwriters — they can qualify you for additional credits.
Smart property technology for better premiums and fewer claims
Insurers are increasingly rewarding property owners who invest in risk mitigation technology. Leak detection sensors, automated shut-off valves, and smart security systems reduce the likelihood and severity of claims, which directly affects your loss of rent exposure. A single water damage event can render a rental unit uninhabitable for weeks. Devices like the eufy S330 Smart Lock or a video doorbell system may seem unrelated to loss of rent, but any technology that prevents or limits damage shortens the period your property is out of commission. Some insurers now offer premium discounts for properties with certified smart technology installed.
Future changes to watch
Market consolidation is reshaping the Canadian insurance landscape. Definity has acquired Travelers Canada, Everest Canada is being purchased by Wawanesa, and Zurich has acquired Beazley. These changes may affect capacity and pricing in the coming years. If your insurer is involved in a merger, your renewal terms could shift — for better or worse. The alternative risk market is also growing, with captives, parametric covers, and structured programs becoming more accessible for mid-sized property owners. These options are worth exploring if traditional loss of rent coverage becomes too restrictive or expensive in your region.

The soft market window won’t last forever
Canadian property insurance is in a rare moment: rates are falling, capacity is abundant, and insurers are competing for quality risks. That gives property owners room to fix coverage gaps that would have been expensive or difficult to address a few years ago. But the same forces that made the market soft — increased competition, lower reinsurance costs, improved insurer loss performance — can reverse quickly after a bad catastrophe season or a shift in global reinsurance pricing. The 67% construction cost increase isn’t going away, and the Emond ruling has permanently changed how compliance costs are handled.
